atomaarista

Atomaarista is the partitive singular form of the Finnish adjective atomaarinen, meaning atomic or relating to atoms. The adjective describes phenomena at the scale of atoms or properties derived from atomic structure. In Finnish, adjectives decline with nouns, and the form atomaarista is used when the object is indefinite or part of a mass noun, or in certain verbal constructions.

Etymology: the stem comes from atomi, the Finnish word for atom, which in turn traces to Greek atomos. The suffix -aarinen forms adjectives that indicate relation or belonging, so atomaarinen translates to “atomic” and atomaarista is the corresponding partitive form.

Usage examples:

- Atomaarista energiaa tarvitaan ydinreaktoreissa.

- Atomaarisia ominaisuuksia tutkitaan materiaalitieteessä.

- Atomaarisessa tilassa elektroni on atomitasolla.

In scientific Finnish, atomaarista is frequently used to modify nouns such as energia, rakenne, ominaisuus, tarkkuus, mittakaava. The plural partitive form would be atomaarisia in phrases like atomaarisia ominaisuuksia. Other inflections follow standard Finnish grammar.

See also: atomi, atomismi, atomillinen. Atomaarista appears primarily as a descriptive term in technical or scientific writing, signaling discussion of properties or effects at atomic scales rather than everyday objects.
